Q. [R Product] How can I switch between uppercase and lowercase letters on the English keyboard?
A.
You can use the uppercase/lowercase keyboard available in the [User Library].
By pressing the Caps Lock button, you can switch between uppercase and lowercase letters.
The Caps Lock functions as a toggle switch that turns a specific bit in the internal address ON/OFF.
Depending on the ON/OFF status of that bit, the system is designed to switch between uppercase and lowercase input accordingly.
